According to the Associated Press, Liz Mair, the aide to Wisconsin Gov. Scott Walker’s political action committee who was critical of Iowa, has resigned. She told AP reporters Tuesday she was leaving Walker’s team just a day after she had been tapped to lead his online communication efforts, citing the distraction created by a series of recent Twitter posts about Iowa’s presidential caucuses.

“The tone of some of my tweets concerning Iowa was at odds with that which Gov. Walker has always encouraged in political discourse,” Mair said in a statement announcing her immediate resignation. “I wish Gov. Walker and his team all the best.”
